V IMPROVEMENT IN IIEIIIIOATING.A SHIPS.

` The Schedule :referred to inthese Letters Patent and making part of the same. "it

.To all whom. it may concern.-

Be it known that we, G. W. CoREYand /THoMAs' 4LOSIE, of the city of N ew York, in the StatefofiNew 4 York, have invented a certain new and useul Improvement in Float-ing Ships and other vessels; :and awe do hereby declare that the following is a full clear, and' vexact description of' the same, reference being had to the accompanying drawing, and to the marks and letters thereon, which said drawing forms part of this specificatiomaud shows a vessel and partsthereof with our improvement thereon- Figure 1 being a top view of the vessel, the upper deck having been removed;

Figure 2, a view, by"`transversc section, atmidship; Figure 4, a view, by like section, nearer the stern of the vessel; and

y Figure 3, a view of a tube and sack to be used in certain parts of' the ship. y

In each `of these figures, where like parts are shown,

I like marks and letters are used to designatethe parts.

` of the vessel, Aas isindicated by'figs. 1, 2, and 4 ofthe drawings.

These tubes will thus occupy'what is simply air space in'ordinary vessels, and, in addition to the buoyancy which they give to the vessel, will provide for a suicient circulation of air to prevent decay and rotting of the timbers, the spaceb between the tubes permitting such circulation of air.

In addition to the tubes here named, we propose to have the bulk-head chambers and all other spaces in the vessel occupied in whole or in part with India-rubber or air-tight elastic sacks,c, connected with tubes d, or a series of tubes, and some proper means for their inflation, so that such chambers or recesses may be used for cargo or stores, which may be removed when necessary, and such chambers, also, be made airchambers, and contribute to the buoyancy and safety of the vessel. l \Ve are aware that life-boats have been constructed with air-tight metal and other chambers and sections, and that the spaces betweenthe timbers and plauking and flooring have been filled with air-sacks and airtight metallic vessels, and we do not, therefore, broadly claim rendering ships an'd other vessels buoyant, and adding to their'safety by usingr such air-tigh`t spaces or chambers; but

What we do claim as our invention, and desire to p l. The series oi' air-tight'tubes passing entirely from the one side of the vessel to the other, 4between thel timbers, and between the plankiug and ooring, andV between the flooring and ceiling of the decks, as andk for the purposes herein recited.

2. The combination of the air-tight sack and tubes,

used as and for the purposes herein set forth.
